No, you still need to write the setter, but make it private.
Like this:
public class Foo {
private String
foo;
public String getFoo() {
return foo;
}
private void setFoo(String foo)
{
this.foo = foo;
}
}

I understand that you're using constructor injection and that they don't
have setters.
What I'm suggesting is that you add private setters and a parameterless
constructor. It won't have any impact on the immutability of your class.
It's a bit of extra code, but not uncommon. I know it's not ideal, but it
would work for the time being.

Re: Parameterised constructors
As a temporary alternative we do support private setters as of 2.2.0. Constructor injection is supported in the .NET version. The two codebases are somewhat similar, so we could always check on their approach to it.

Re: Parameterised constructors
Mmm ... no that's not quite it.
I have a set of VO classes that are immutable. This means that all the data
is added at construction.

I am not finding docs for it at the moment, either. I think that the
ResultObjectFactoryTest unit test does what you want. Take a look, and
